Zipper and Closure Application Verification Log

Inspection log for resealable pouch zipper and closure application. Confirms zipper alignment, seal integrity, and open-close function before the run continues.

Run Identification

• Line, machine, and shift identified
  Record the production line, machine ID, and shift for traceability.
• Product SKU, pouch style, and zipper type recorded
  Document the product being run, pouch format, and closure style.
• Sample lot or roll number recorded
  Capture the material lot, roll, or batch identifier used for the verification.
• Verification time recorded
  Record the date and time the closure verification was completed.
• Operator or inspector identified
  Record the person completing the verification.

Zipper Alignment and Placement

• Zipper is centered and aligned to pouch opening
  Verify the zipper track is straight, centered, and positioned consistently across the pouch width.
• Zipper ends are fully seated and not twisted
  Check both ends of the closure for proper seating, no twisting, and no visible misplacement.
• Closure application is consistent across sampled pouches
  Rate consistency of zipper placement and application across the sample set.
• No visible wrinkles, gaps, or puckering at closure area
  Inspect the closure zone for wrinkles, gaps, puckering, or other application defects.

Seal Integrity and Function

• Seal is continuous and uniform along the closure area
  Confirm the seal around the zipper and pouch opening is continuous, even, and free of breaks.
• No visible channels, leaks, or incomplete fusion
  Check for channels, open paths, leaks, or incomplete sealing at the closure interface.
• Open-close function operates smoothly
  Open and reclose the pouch to verify the zipper engages and disengages without excessive force.
• Closure remains engaged after repeated open-close cycles
  Cycle the closure multiple times and confirm the zipper still locks securely and does not pop open.

Defects, Disposition, and Release

• Defects observed
  Select all defects observed during the verification.
• Non-conformance documented and communicated
  Confirm any defect was documented and escalated according to site quality procedure.
• Corrective action taken before run continues
  Describe the action taken, such as machine adjustment, sample hold, or material replacement.
• Inspection disposition
  Record the outcome of the verification.
